Houston residents can expect another couple of rainy days, with a severe weather threat in place Friday night and Saturday morning.

The greatest threat is to the areas northeast of Houston, closer to the Arkansas-Louisiana-Texas borders, according to the National Weather Service.

If severe storms form, hail could be greater than 1 inch in diameter, and wind gusts could reach speeds of 60 mph. Those storms would likely take place between 9 p.m. Friday and 6 a.m. Saturday, meteorologists said.

The Houston Office of Emergency Management urged caution in case the storms reach the Houston area.

"Heads up! We may have some severe storms overnight into Saturday morning," the office tweeted. "Keep a flashlight by your bedside in case of power outages, secure outdoor objects, and stay indoors during periods of severe weather."

Thunderstorms are possible in Houston after 1 p.m. Friday, although the chances increase into the night. Thunderstorm chances will also continue into Saturday.

A cold front is also forecast, with temperatures expected to fall to 58 degrees by 5 p.m. Saturday and to 48 degrees by Saturday night.
